INSTALLATION CONSIDERATIONS
CONTINUED
If you are going to use the optional
Niles Rear Wave Enclosure, you will
need an additional 2” of depth and
10” clearance to one side of the
loudspeaker opening.
NOTE: BE VERY CAREFUL WHEN LOCATING
THE SPEAKERS. VERIFY ALL LOCATIONS
ARE CLEAR OF OBSTRUCTIONS BEFORE
CUTTING THE FIRST HOLE.
Each speaker requires two-conductor wiring of sufcient gauge. The gauge
depends on the length of the wire. For recommendations, please refer to (Figure 2).
(Stereo Input loudspeakers require four-conductor wiring).
When running loudspeaker wire inside walls or ceilings, use special jacketed
cable (CL-2 or CL-3 rating) to protect the wire and for re prevention. In some
municipalities, conduit is required. For a trouble-free installation, low voltage wire
such as loudspeaker wire must be in accordance with the National Electrical Code
and any applicable provisions of the local building code. If you are unsure of the
correct installation techniques, wire jacket, or type of conduit to use, consult a
professional audio/video installer, building contractor, or the local building and
inspection department.

INSTALLING THE LOUDSPEAKERS
It is often easier to lay the speakers out on the oor and then transfer the
locations to the ceiling with a laser plumb bob. If you are using new construction
brackets, place string across the centers of the bracket to provide a way to align
the bracket to the laser. Remember, you will need 1” to the sides of the mounting
hole for the mounting clamps to secure the speaker to the drywall.
1. Once you have determined a possible position for the hole cutout, drill a
1/8” pilot hole just barely through the ceiling (1/2” to 5/8” deep in most
homes) in the center of your proposed loudspeaker location. BE VERY
CAREFUL NOT TO DRILL THROUGH EXISTING WIRES, PIPES, OR
STRUCTURE. IF YOU FEEL ANY EXTRA RESISTANCE AS YOU ARE
DRILLING, STOP.
2. Cut a foot-long piece of coat hanger. Bend the wire (creating a right
angle) leaving 5-1/2” at one end (this allows for the extra width of the
mounting dogs). Poke the “L-shaped” wire into the pilot hole and turn it
in a complete circle and move it into the ceiling cavity to make sure you
have approximately 6” of depth. If the wire’s movement is obstructed by
anything, fill the hole(s) with spackle and try another location. (If there
is any risk of uninsulated electrical connections within the ceiling area,
use insulating gloves or other materials or consult with an installation
professional before proceeding).
3. If the coat hanger moves freely in a complete circle and you have
sufficient depth, tape the template to the ceiling and proceed to layout the
other speakers. Once you are comfortable with all speaker locations, use
a pencil to lightly outline the circular template.
4. Drill the starting point of your cut with a 1/4” bit.
5. If you are cutting drywall, use a sheetrock or keyhole saw. Cut the hole
with the saw at a 45° angle. That way the drywall section can be replaced
cleanly if there is an unseen obstruction behind the wall. IMPORTANT: BE
VERY CAREFUL NOT TO SAW THROUGH EXISTING WIRES, PIPES,
OR STRUCTURE. IF YOU FEEL EXTRA RESISTANCE AS YOU ARE
CUTTING, STOP.
NOTE: DO NOT INSTALL LOUDSPEAKERS BEFORE THE DRYWALL HAS BEEN COMPLETELY
FINISHED AND PAINTED.

INSTALLING THE LOUDSPEAKERS

6. Prep the speaker wire by stripping 1/4”-1/2” from each speaker lead.
Twist the strands or tin the leads with solder to ensure there are no stray
strands that could short and possibly harm the amplifier.
7. If you’ve chosen to use insulation behind the loudspeaker, place it through
the hole and center it on the opening. If using paper-backed insulation, it
should be placed so that the paper side is away from the loudspeaker.
8. The speaker has black and red
spring-loaded connectors (Figure 3).
Black is for the negative (-) wire and
red for the positive (+). It is important
to observe correct wiring polarity.
This is especially important for the
Stereo Input (SI) Loudspeaker. If
you have wire other than black and
red, make sure you connect it the
same on the amplifier end as the
speaker end. Failure to do so will
adversely affect the loudspeakers’
performance.
9. Once the speaker wires are
connected, carefully slide the
loudspeaker into the opening hole
(Figure 4). While holding the speaker
in place, tighten the mounting screws
to secure the speaker to the drywall.
We recommend using a motorized
screwdriver. Be careful not to over
tighten. The DS loudspeakers feature
spring loaded mounting clamps that
allow the speaker to remain flush
with the ceiling, even if the
drywall shifts or expands.
NOTE: DO NOT CARRY THE SPEAKER
BY THE TWEETER OR TWEETER
BRIDGE. THIS MAY DAMAGE THE
SPEAKER.

ADJUSTING THE PIVOTING WOOFER AND TWEETER
DS loudspeakers feature the patented Directed Soundeld™ woofer pivot
mechanism that enables the loudspeaker to direct the sound to the listening area
(Figure 5). The tweeter(s) pivot independently of the woofer to provide additional
control of the sound. Adjusting the woofer angle will affect the tweeter angle, so
always begin by adjusting the woofer.
1. Press the outside edge of the woofer on the plastic, not the rubber, and
slide the speaker until it is facing the primary listening position. The
woofer adjusts approximately 15-degrees. Do not force the speaker.
2. After adjusting the woofer, adjust the tweeter by pressing on the outside
edge of the tweeter to point to the listening area.

SWITCH ADJUSTMENTS
TWEETER SWITCH
(DS7MP, DS7PR, DS7HD, DS8PR, DS8HD, DS7SI)
The three-position tweeter switch allows you to adjust the high frequency output
of the loudspeaker to compensate for room acoustics. The center position does
not affect the tweeters output. Moving the switch to the – position reduces the
tweeter output by 3 dB to compensate for bright rooms (tile or wood oors, spare
furnishing, tall ceilings). Moving the switch to the + position increases the tweeter
output by 3 dB to compensate for absorptive rooms (carpeting, lots of drapery,
plush furniture, etc.).
DIALOG COMPENSATION SWITCH
(DS7MP, DS7PR, DS7HD, DS8PR, DS8HD, DS7SI)
This switch provides additional denition at critical midrange frequencies where
the human voice is reproduced. This switch is generally used only for home
theater center speaker applications. Engage the switch if you wish to enhance
the dialog.
DIFFUSE / DIRECT SWITCH
(DS7FX, DS8FX)
Use the Diffuse setting for movies and general music listening since most lms
are mixed using non-localized surround effects and music is usually recorded in a
favorable acoustic environment. Use the Direct setting for discrete multi-channel
recordings that equally emphasize front and surround sounds. For 7.1-channel
surround sound systems, use the Diffuse setting on the side effects loudspeakers
and the Direct setting for the rear effects loudspeakers.
PAINTING THE GRILLES
The DS loudspeaker grilles can be painted without priming, but the fabric scrim
must rst be removed. The installation template has die cut standoffs that can be
used to position the grille off the ground while painting. Use several light coats
sprayed from different sides and angles to cover all surfaces and not ll in any
holes. If you do ll some holes, use compressed air to open them before the paint
dries. It may be helpful to dilute the paint.
INSTALLING THE GRILLES
The Niles MicroThin™ speaker grille installs magnetically over the speaker.
Carefully center the grill over the speaker and let the magnets do their work,
verifying that the grill sets ush against the ceiling at all edges.

APPLICATIONS
Niles DS Loudspeakers are designed to be installed in any standard ceiling.
When choosing a location, thought should be given to the sound coverage of the
loudspeaker, and ease of running the speaker wire.
STEREO SOUND APPLICATIONS
The best stereo effect will be achieved if both
loudspeakers are at an equal distance from the
listening area. Ideally all loudspeakers should
be on the same horizontal plane (Figure 6). Avoid
installing loudspeakers near corners to prevent
a “boomy” or diffracted sound. Also note that
the lower the ceiling, the closer the loudspeaker
should be placed to the listener.
HOME THEATER APPLICATIONS
Left/Center/Right – Position the center
channel loudspeaker directly over the
television, with the left and right speakers
equidistant from the center. The separation
between the left and right should not be
more than the distance to the primary
seating area (Figure 7).
Side Surround Effects – Position surround
effects loudspeakers to the sides of the
listening area with the tweeters in-line with
the listener. The tweeters should point to
the front and rear of the room (Figure 7).
Rear Surround Effects – Position surround
effects loudspeakers behind the listening
area, to the inside of the front left and right
speakers. The tweeters should point to the
sides of the room (Figure 7).

APPLICATIONS
CONTINUED
SINGLE SPEAKER STEREO INPUT APPLICATIONS
Stereo Input loudspeakers are ideal for small rooms where positioning two
loudspeakers is not practical. Examples would be a small kitchen, bathroom,
hallway, or small bedroom. Locate the loudspeaker as close to the center of the
room as possible for the most even distribution of sound (Figure 8). Avoid installing
the loudspeaker near a corner to prevent a “boomy” or diffracted sound.
